<h2>ALDH2 markers and Alcoholism</h2>

<h3>Description</h3>

<p>This data set contains eight ALDH2 markers and Japanese alcohlic
patients (y=1) and controls (y=0). There are genotypes for 8 loci, with a prefix 
name (e.g., &quot;EXON12&quot;) and a suffix for each of two alleles (&quot;.a1&quot; and &quot;.a2&quot;).
</p>
<p>The eight markers loci follows the following map (base pairs)
